Cleaning RPM db
Sometimes, RPM gets stuck. Read this http://people.redhat.com/berrange/notes/rpmrecovery.html or simply remove /var/lib/rpm/_ _db* will do the trick.Repackage
Install a package from an older versionrpm -Uvh --oldpackage foo-1-1.i386.rpm
Repackage the old package before upgrading the new one
rpm -Uvh --repackage foo-1-2.noarch.rpm
Remove package with rollback info
rpm -e --repackage foo
Rollback the upgrade
rpm -Uvh --rollback '2 hours ago'
